Pain intensity is the domain most often assessed in pain research. Although the Numerical Rating Scale is recommended for use in western countries, the utility and validity of this scale, relative to others, has not been established in non-western developing countries, such as Nepal. ⋯ The findings indicate that the Faces Pain Scale-Revised should be the first choice for assessing pain intensity in Nepalese adults. Research is needed to determine whether these findings replicate in other non-western and developing countries, to identify the pain intensity measure that would be the best choice for use in cross-cultural pain research.

Review Meta Analysis Comparative Study
A Comparison of the Assay Sensitivity of Average and Worst Pain Intensity in Pharmacologic Trials: An ACTTION Systematic Review and Meta-Analysis.
Identifying methods to improve assay sensitivity in randomized clinical trials (RCTs) may facilitate the discovery of efficacious pain treatments. RCTs evaluating pain treatments typically use average pain intensity (API) or worst pain intensity (WPI) as the primary efficacy outcome. However, little evidence is available comparing the assay sensitivity of these 2 measures. ⋯ Twenty-seven active versus placebo comparisons were identified in 23 eligible articles. Using a random-effects meta-analysis, API SES and WPI SES did not differ significantly (difference = -.021, 95% confidence interval = -.047 to .004, P = .12). The findings indicate that, depending on the objectives of the study, either API or WPI could be used as a primary outcome measure in clinical trials for the chronic pain conditions included in this analysis.

Randomized Controlled Trial Comparative Study
Patient-Controlled Paravertebral Block for Video-Assisted Thoracic Surgery: A Randomized Trial.
Paravertebral block (PVB) has been proven to be an efficient way to control postoperative pain in patients who have undergone a thoracotomy. This study explored whether the use of a patient-controlled PVB can provide benefits over intravenous patient-controlled analgesia (PCA) for 3-port single-intercostal video-assisted thoracic surgery. ⋯ PVB, which resulted in lower cumulative dezocine doses and produced fewer side effects than PCA, can provide effective pain relief for patients undergoing video-assisted thoracic surgery.

Multicenter StudyAssessment of Nociception and Pain in Participants in an Unresponsive or Minimally Conscious State After Acquired Brain Injury: The Relation Between the Coma Recovery Scale-Revised and the Nociception Coma Scale-Revised.
To investigate the relation between consciousness and nociceptive responsiveness (ie, Nociception Coma Scale-Revised [NCS-R]), to examine the suitability of the NCS-R for assessing nociception in participants with disorders of consciousness (DOC), and to replicate previous findings on psychometric properties of the scale. ⋯ We report a strong relation between the responsiveness to nociception and the level of consciousness. The NCS-R seems to be a valuable tool for assessing nociception in an efficient manner, but additional studies are needed to allow recommendations for clinical assessment of subjective pain experience.
